PROBLEM TO BE SOLVED: To provide an information printing paper to be used in image printers, capable of eliminating bleeding through blocking horizontal ink flow for water- based ink and affording good print uniformity. SOLUTION: This information printing paper is such as to contain an internal sizing agent and a filler and coated with a coating liquid; wherein the internal sizing agent is an alkenyl ketene dimer polymer stabilized with either polyamidoepichlorohydrin or polydiallyldimethylammonium chloride(DADMAC) (polymer-stabilized alkenyl ketene dimer), the filler is wet-ground CaCO3 or precipitated CaCO3 , and the coating liquid comprises (a) at least one of oxidized starch, cationic oxidized starch, and enzyme-modified starch, (b) a styrene-acrylic emulsion(SAE) and (c) common salt. |
